Now I am speaking to you Gentiles. Inasmuch then as I am an apostle to the Gentiles, I magnify my ministry  in order somehow to make my fellow Jews jealous, and thus save some of them. For if their rejection means the reconciliation of the world, what will their acceptance mean but life from the dead? If the dough offered as firstfruits is holy, so is the whole lump, and if the root is holy, so are the branches.

And David says,  

“Let their table become a snare and a trap,

How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching? And how are they to preach unless they are sent? As it is written, “How beautiful are the feet of those who preach the good news!” But they have not all obeyed the gospel. For Isaiah says, “Lord, who has believed what he has heard from us?” So faith comes from hearing, and hearing through the word of Christ. 

But I ask, have they not heard? Indeed they have, for  

“Their voice has gone out to all the earth,

and their words to the ends of the world.” 

But I ask, did Israel not understand? First Moses says,  

“I will make you jealous of those who are not a nation;

with a foolish nation I will make you angry.” 

Then Isaiah is so bold as to say,  

“I have been found by those who did not seek me;

I have shown myself to those who did not ask for me.”

But of Israel he says, “All day long I have held out my hands to a disobedient and contrary people.”

Romans 10:5-13 (ESV): For Moses writes about the righteousness that is based on the law, that the person who does the commandments shall live by them. But the righteousness based on faith says, “Do not say in your heart, ‘Who will ascend into heaven?’ ” (that is, to bring Christ down) “or ‘Who will descend into the abyss?’ ” (that is, to bring Christ up from the dead). But what does it say? “The word is near you, in your mouth and in your heart” (that is, the word of faith that we proclaim); because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes and is justified, and with the mouth one confesses and is saved. For the Scripture says, “Everyone who believes in him will not be put to shame.” For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. For “everyone who calls on the name of the Lord will be saved.”

Now if Christ is proclaimed as raised from the dead, how can some of you say that there is no resurrection of the dead? But if there is no resurrection of the dead, then not even Christ has been raised.  And if Christ has not been raised, then our preaching is in vain and your faith is in vain.  We are even found to be misrepresenting God, because we testified about God that he raised Christ, whom he did not raise if it is true that the dead are not raised.  For if the dead are not raised, not even Christ has been raised.  And if Christ has not been raised, your faith is futile and you are still in your sins.  Then those also who have fallen asleep in Christ have perished.  If in Christ we have hope in this life only, we are of all people most to be pitied. 

But in fact Christ has been raised from the dead, the firstfruits of those who have fallen asleep.

And Isaiah cries out concerning Israel: “Though the number of the sons of Israel be as the sand of the sea, only a remnant of them will be saved, for the Lord will carry out his sentence upon the earth fully and without delay.” And as Isaiah predicted,  

“If the Lord of hosts had not left us offspring, we would have been like Sodom and become like Gomorrah.”
